New "Green Bomber" Sea Worms Fire Glowing Bombs
The glowing bombs are thought to distract predators such as fish, allowing the worms to escape.
"There are no other annelids that have structures like this," said Karen Osborn, a marine biologist at the Scripps Institution of Oceanography in California. The annelids make up a large category of marine and terrestrial segmented-worm species, including common earthworms.
She and colleagues describe one of the new species, Swima bombiviridis--"swimming green bomb"--in tomorrow's issue of the journal Science.
